Title: Isamu Yanai: Innovator in Shell-and-Tube Reactor Technology

Introduction

Isamu Yanai is a notable inventor based in Yokosuka, Japan. He is recognized for his contributions to the field of chemical engineering, particularly in the design of shell-and-tube reactors. His innovative approach has led to advancements in the production of important chemical compounds.

Latest Patents

Yanai holds a patent for a shell-and-tube apparatus that features an intermediate tube plate. This apparatus is designed to section the interior of the vessel into compartments with varying temperatures. The heat transferring tubes penetrate the intermediate tube plate, allowing a fluid to pass through and be heated or cooled by a surrounding heat transfer medium. The inclusion of insulation plates helps to create a stagnation zone for the heat transfer medium, which minimizes thermal stress and enhances efficiency. This reactor is particularly beneficial for the production of (meth)acrylic acid and (meth)acrolain through catalytic gas-phase oxidation of propylene or butenes.
